A giant solitary nodular trichoepithelioma (GST) is a rare trichogenic tumor, which may present as a pigmented lesion. A 45-year-old female was diagnosed as having a giant solitary nodular trichoepithelioma on her right forearm. About 11 cases have been reported in literature. Our case is the 2nd largest of all reported cases and, so far, GST of the forearm has not been reported in literature. The recognition of GST is important because of its close resemblance to basal cell carcinoma and other skin adnexal tumors, both clinically and histopathologically
